Endocrine

The body maintains its normal function by a number of checks and balances and feedback loops. Hormones are the messengers that help make adjustments in the body's function. There are connections between the pituitary gland in the brain and glands in he body to help regulate function.

Any adrenal gland abnormalities can cause a decrease in the cortisone hormone levels in the body. Low blood pressure is also seen in this situation.

Abnormally low pituitary function will also cause low blood pressure

People with diabetes may develop low blood pressure when their blood sugar drops too low. If the blood sugar gets too high (hyperglycemia), dehydration and low blood pressure may also occur through a different mechanism.
